Milltek muffler technology

[|Maku|]

Hello!


Ive been wondering what sort of mufflers aftermarket suppliers use. For example Milltek. As I have read from this forum Milltek RS2 exhaust is not boomy at all and we know that many tuners advise Milltekk stuff as well. I'm sure that many of you have read this article, what showed again that straight through mufflers are the best performance mufflers. But what was interesting that a good straight through muffler wasn't very much nosier than factory muffler.

In curiosity I looked into S5 muffler and it looked like THIS. So I can imagine that it has some kind of open chamber in there or smth. I also presume that n/a and forced induction engine mufflers are different.

So does anybody know what sort of mufflers Milltek use? Lets take RS6 for example. What Milltek does differently from stock exhaust?


Thanks for those who share their thoughts,

I doubt you could find out easily, someone like Milltek will keep info like that to themselves for obvious reasons!
If everyone knew how they made them, cheaper copies would soon appear

To make cheaper copies all is needed to cut one type muffler apart to understand whats in there. Also, if muffler is straight through you can see it from outside. Then only question remains what absorption materials have been used to reduce noise.

have a look on summitracing.com get a catalogue

they do lots of mufflers and have images of the cut open.

some look like a maze inside.

Actually all Im asking is someone to take a picture of his RS2 Milltek mufflers so that we can see is it straight through or not. Would be even better if anyone knows what absorption materials have been used.

Thats what I meant though, obviously anyone can cut one open to copy it, but as you said, its the materials they use that will be the secret!

i don't think there is any secretive witchcraft behind it, just lots of R&D to find the appropriate sized / type of muffler that does not resonate badly and gives a decent increase in flow for any particular model. Things like pipe size, pipe length between mufflers, muffler size and diameter, differential sizes between mufflers are what will affect tone, resonance , booming etc. Its experience & trial and error

This is my point!
Time, effort, cost and research... they are not going to freely give away their findings!

why would they need to - just copy their product.

It's not a computer disk, it's not so easy to copy.

It's like people trying to copy ECU chipsets thinking they can learn about them and modify them, it aint so easy to do!

So why are there not already cheaper but just as good/same sound as Milltek available for example?

[GazzaG60]

id say its fairly easy for a skilled metal worker to replicate. sure they will know what materials are in there. whether you would want to is another thing.

id say its down to supply and demand Dest.

This is how S4 2.7biturbo Milltek rear muffler looks like, obviously straight through.

Turbo cars dont need back pressure just noise absorbtion

N/A cars have to have some back pressure to perform better.
